If EN2 goes high after the step down converter is already enabled, then the delay DLY2 starts when EN2 goes
high. See Figure 20.
Figure 20. Power-on Sequencing Using EN1 and EN2
Connecting an external capacitor to the DLY1 and DLY2 pin sets the delay time. If no delay time is required
these pins can be left open. To set the delay time the external capacitor connected to DLY1 and DLY2 is
charged with a constant current source of typically 5
A. The delay time is terminated when the capacitor voltage
has reached the internal reference voltage of VREF=1.280 V. The external delay capacitor is calculated using
where td = Desired delay time
Example for setting a delay time of 5.3 ms:
